My invention relates to improvements in lighters and more particularly,has reference to means associated with a gas burner, such as for aBunsen flame employed in dental operations, usually adjacent theoperating chair and is intended to ignite the gas without the use ofmatches.

In the accompanying drawings, I have illustrated a suitable applicationof my invention as associated with the work tray or table, generallypivotally mounted. in adjustable relation to the chair. Referringthereto, Fig. 1 illustrates the same in perspective, parts being brokenaway. Fig. 2 is an enlarged sectional elevation of the burner, guard orwork holder and a side view of the lighter, on the line Z-2 of Fig. 1.Fig. 3 is a perspective view of the lighter, as a removable attachment,adapted for right or left-handed use and for clockwise andcounterclockwise operation. Fig. 4 is an enlarged sectional elevation ofthe same on the line 44 of Fig. 3. Fig. 5, is a side elevation of apreferred form of replaceable flint-wheel. Fig. 6 is a section on theline 6-6 of Fig. 3, showing pockets or holes for removably securingextra flints for use in the lighter and Fig. 7 is an enlarged sideelevation of part of a preferred form of flint cutting wheel.

1 indicates a conventional form of adjustable table for the dentaltools, etc. pivotally mounted on arms, 8', as shown, and arm 8 may bemounted upon the usual standard or support (not shown), through whichthe gas is supplied to the Bunsen, through burner tube 9, with air valveII, which regulates the mixture of air and gas by rotation of sleeve H),to expose or cover, more or less, port H, a predetermined amount. I2 isthe gas orifice or burner and I3 is a cup-like guard and supportsurrounding the orifice and held on the burner as indicated at l4, l5.

The lighter standard is indicated at 16 and is provided with passage [1,for flint-wheel l8, rotatably mounted therein, upon shaft 19, having asquare inner end 20, engaging a square hole in the wheel I8, and a roundhole at 2| in the lighter standard I6, 22 indicating an annular recessor channel 22 in shaft 19 for ball 23, projected by compression spring24, beneath threaded cap 46, to hold and lock said shaft while itengages wheel [8.

The standard N5 of the lighter may be provided with a rounded baseprojection IE, to rotatably engage hole 25, in the ring support 28, ofthe lighter and may be provided with diametrically opposed recesses orpockets 21, 28, for ball 29, projected by spring 30, in pocket 3|, withplug 3|, beneath ring 26, to permit standard l6 to be rotatated aboutand held in its adjusted position by ball 29, the housing 30' beingfixed with relation to ring 26, and serving to retain the standard inits adjusted position, according to the seating of ball 29 in pocket 21or 28. The periphery of wheel l8 may be out spirally and axially ortransversely, as shown in Fig. 5, to provide cutters with radial walls42 at the cutting sides and substantially tangential walls 43 at thetrailing sides thereof, as shown.

In operation, the expansion ring 26, provided with radial cuts 31, iscompressed when forced into the bottom of the cup-guard or support l3,where it is thus frictionally held when released. A flint 38 may then betaken from a reserve pocket 39, and after plunger 32 has been raisedagainst spring 36 and turned by button 35 and seated in recess 40, aflint 38 is dropped into chute 35, where it comes to rest upon theexposed surface of flint-wheel l8 and is held by ofiset 34, as shown. Bynow turning on the gas at 45, then rotating the wheel 18, by turning theknurled finger piece 4|, sparks from the end of the flint l8 aredischarged from the cutting surface of the wheel 18 in the path of theescaping gas, which is thereby ignited and this mode of operationfollows, whether shaft l9 projects rightwardly or leftwardly from guardl3, the pockets 21, 28, and ball 29, serving to frictionally hold thelighter standard H5 in position according to the adjustment made.

Of course it will be understood that various modifications may be madein the construction without departing from the spirit of the invention,as claimed.

I claim:

1. In combination with a dentists lamp having the usual guard with alateral opening through the side thereof, a lighter having a split ringbase within, conforming to and frictionally engaging a bottom portion ofsaid guard, a lighter standard thereon, a scratch-wheel and flint insaid standard, and means extending through said opening for operatingsaid lighter.

2. The lighter specified in parent claim 1, wherein said base comprisesa split ring wider at the top than at the bottom.

3. The lighter specified in claim 1, having means for removably securingsaid standard upon said base.

4. The lighter specified in parent claim 1, havin flint feeding meanscomprising a resiliently projected plunger with an offset adapted toengage and feed said flint and means for releasing said plunger andflint for replacing the latter.

5. The lighter specified in parent claim 1, having resilient ballengaging means for rotatably engaging and for releasing said lighteroperating means.

6. The lighter specified in parent claim 1, having resilient ballengaging means for holding and releasing said standard.
